Brown Spots

What are Brown Spots on the Eye?

• Brown spots on the eye, also known as ocular melanocytosis or eye freckles, are pigmented areas that develop on different eye parts.
• These spots are typically brown or black and can appear on various structures within the eye, including the Iris, sclera (white part of the eye), and the conjunctiva (thin membrane covering the front of the eye).
• These spots are primarily composed of melanocytes, cells responsible for producing melanin, the pigment that gives color to our skin, hair, and eyes.

Types of Brown Spots:

Iris Nevus

• On the Iris, the colored portion of the eye, the brown specks are freckles. They rarely harm people and don’t interfere with vision.

Ocular melanosis

• It refers to the pigmentation of the conjunctiva. The thin membrane covers the front of the eye.
• It can cause brown or black spots on the conjunctiva. While ocular melanosis is usually benign, it should be monitored by an eye specialist.

Pterygium

• It is a tissue growth that has the potential to spread from the cornea to the white area of the eye.
• It may have a brown or yellowish appearance and can sometimes be associated with exposure to UV radiation. It can cause discomfort and irritation. ⁸ Understanding Brown Spots| Researched based study from National Institutes of Health

Ocular Melanoma

• It is a rare but severe type of cancer that can develop in the eye, including the iris, choroid, or ciliary body.
• It may cause brown or dark patches to appear in the vision. It requires prompt medical attention and treatment. ² Understanding Brown Spots| Researched based study from National Institutes of Health

• The pigmentation of eye structures, such as the iris and sclera, can vary over time as a result of cumulative UV exposure and other environmental influences.

Medical conditions

• Certain medical conditions, such as ocular dermal melanocytosis (Nevus of Ota), can increase the likelihood of developing them.
• These conditions are characterized by excess melanocytes in and around the eye, leading to pigmentation changes. ³ Causes| Researched based study from National Institutes of Health ,⁴ Causes| Researched based study from National Institutes of Health ,⁵ Causes| Researched based study from National Institutes of Health ,⁸ Causes| Researched based study from National Institutes of Health
